You collect goods from Depot - basically it means you can split delivery in multiple attempts.
Which I find a good thing.
If it is like the wing deliveries, you have to hold the + button from 0. At least it fills geometrically and not a constant 1 at a time.That makes sense. Finally something other than a python can complete those "take 180 tons to an outpost" missions, or you can accept a stack of missions and then switch to your hauling ship.
Please tell me the "amount to collect/deliver" slider starts at the maximum amount instead of zero so I don't have to scroll the bar over...
